Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
thuc va » thuc vat, thuc dan, thuc day
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
va cao » va co, va dao, va bao
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang x hoi. lieu ((va cao) or (va cac)) thuc va thanh vai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. lieu ((va cao) OR (va cac)) thuc va thanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. lieu ((va cao) or (va cac)) thuc va thanh vai ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. lieu ((va cao) or (va cac)) thuc va thanh vai ((cua tre) OR (cua te))*.
